| Se presenta la composicion, abundancia y distribucion del ictioplancton obtenido en la campana del BIP Dr. Eduardo L. Holmberg EH-04 04 03 realizada en octubre de 2003 Instituto Nacional de Investigacion y Desarrollo Pesquero INIDEP, Argentina). Se efectua una comparacion con datos obtenidos en otras campanas realizadas en la zona alrededor de las Islas Malvinas Argentina, Atlantico SO , en primavera desde 1996 hasta 2003. Se describe la variacion de la extension de las areas de puestas y cria en los distintos anos. Se han identificado huevos de peces en el 42 por ciento de las muestras que pertenecen a Coelorynchus fasciatus, Micromesistius australis, Salilota australis y Sprattus fueguensis y larvas en el 75 porciento de las muestras, pertenecientes a... |

| Phylogenetic relationships among 24 genera of Rosaceae subfam. Maloideae and Spiraeoideae are explored by means of a cladistic analysis; 16 morphological and anatomical characters were included in the analysis. Published suprageneric classifications and characters used in these classifications are briefly reviewed. Additionally, some new features are here reported, such as seed shape, presence or absence of endosperm, and number of cell layers in the seed coat and in the endosperm. Parsimony analyses indicate that Eriobotrya and Rhaphiolepis form a well-supported clade that is the sister to the remainder of the subfamily. This result is in agreement with published ITS sequence data. Other clades are not supported, with the exception of the group... |

| The sections Azorelloida, Neoandina, and Paramensia of Geranium, all of them from the Andes, are taxonomically revised. Fruits with the ‘seed ejection-type’ dispersal have been found in all species, which allows classifying them within subg. Geranium. The sections Azorelloida and Paramensia consist of one and two species respectively, while section Neoandina comprises 24 taxa. Prior to this revision, the stemless species of Geranium from the Andes have been considered to belong to sect. Andina. Geranium sessiliflorum (type of Geranium sect. Andina), however, should be included in sect. Chilensia. Therefore, recently a new sect. Neoandina has been described to include most of the sect. Andina species (Aedo, 2000). Diagnostic morphological features are... |
